A spark from an electric drill is believed to have ignited chemicals used in silicon products, causing a fire at a commercial business at 1387 Clarendon Ave., said Battalion Chief Jeff Magee.

The call came in just before 10 a.m. Tuesday, and city firefighters extinguished the fire within minutes.

Magee said five-gallon buckets of silica, polydimethylsiloxane, benzenesulfonyl hydrazide and a non-dusting paste caught fire at Canton Ohio Rubber Specialty Products. Firefighters evacuated and ventilated the area because of the inhalation hazard but workers were able to return to work after a health check.
